Hurricane Isaias made landfall at 11:15PM EDT Monday August 3 as a category 1 hurricane near Ocean Isle, NC. Maximum sustained winds over 75 mph with peak gusts to near 100 mph were observed. As Isaias accelerates north through the Mid-Atlantic/Northeast US Tuesday, attention turns to inland flooding in the I-95 megalopolis, tornado activity to the northeast of the storm center, moderate coastal storm surge, power outages along the East Coast and an expansion of the wind field as Isaias transitions into an extratropical storm tomorrow over the Canadian Saint Lawrence Valley.
Ongoing Impacts for the Mid-Atlantic & Northeast US
As Isaias accelerates into the Northeast US, the storm is only slowly losing intensity as it begins the process of transitioning into an extratropical storm. Several key concerns are illustrated below.
Initial Assessment of the Carolinas
The peak wind report was from a WeatherFlow sensor in the Cape Fear River, NC, which had a peak gust at 99 mph. Meanwhile, the maximum sustained wind recorded at landfall was Oak Island, NC where a sustained wind of 76 mph was observed. These statistics rank Isaias as the second strongest hurricane to impact this portion of the North Carolina coastline in the last 7 years, behind Hurricane Florence from 2018.
Guy Carpenter meteorologist Jeff Schmidt was in the eyewall of Isaias in Carolina Beach, NC and has observed slight damage as indicated below.
Power outages will continue to build throughout the day as damaging winds continue further north. As of 10AM EDT, initial media reports indicate over 600,000 customers were without power from North Carolina through New Jersey.
